Team Services programmatic access is working for some users without credentials - why?

Question

We have recently upgraded to VS 2017 and Visual Studio Team Services.

We have a set of automated tools that perform various source control related tasks on behalf

Answer 1

Check this registry path: HKEY_CURRENT_USER\Software\Microsoft\VSCommon\14.0\ClientServices\TokenStorage\VisualStudio\VssApp (Tested in VS2017, it stores in 14.0 too)

You also can check credential manager.

On the other hand, you can change storage key:

var c = new VssClientCredentials();
c.Storage = new VssClientCredentialStorage(storageKind: "VssApp2", storageNamespace: "VisualStudio");
TfsTeamProjectCollection _tfs = new TfsTeamProjectCollection(u, c);
